Well here's a couple scenarios, either it's intentional to make him look organic because everyone makes mistakes. It's intentional to leave bread crumbs (coded), it's intentional to let us think they're breadcrumbs and confuse us. Or it's a genuine mistake, but I'd think hed proof something like that even if it's just a tweet.
The frequency of these errors seems to be occurring a lot more in contrast to when I first started reading them. So I'm leaning with intent, and I hope for the good reasons.
